OXYAGETYLENE LIGHTER.

Specification of Letters Patent.

Patented May M09 Application filed April 19, 1921. Serial No. 462,759.

Be it known that I, NAroLnoN G. LA vroNn, a citizen of the United States, residing at Virginia, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Oxyacetylene Lighters; and I do hereby declare the following to be a. full, clear. and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a lighter or lighting device adapted to be secured to a flame torch such as the well known cutting or welding torch. These torches, as ordinarily constructed, use a liquid or gaseous fuel which is projected from a nozzle by compressed air with which the said fuel is commingled. After the air and. fuel is turned on the torch. must be lighted. It frequently happens that these torches are accidentally extinguished by the supply of fuel being cut off or by air being trapped in the fuel conduit and the torch must then, of course. be re-lighted. Much time is often lost by the workmen stopping to secure a match or some other lighting implement to re-light the torch.

It is an object of this invention. therefore, to provide a lighting device carried on a suitable bracket which can be readily attached to the nozzle of the ordinary torch.

It is a further object of the invention to provide such a bracket which can be moved to bring the lighting device into correct lighting relation to the torch and can then be swung into an inoperative position where it will not intefere with the normal operation of the torch.

These and other objects of the invention will be clear from the following description made in connection with the accompanying drawings in which like reference characters refer to the same parts throughout the different views, and in which Fig. 1 shows one form of lighter applied to the nozzle of the torch, the lighter being shown in inoperative position in dotted lines;

Fig. 2 is a perspective view of a detail of the lighter bracket;

F 3 is a sectional view showing a portion of the lighter structure; and

Fig. 4 is a modified form of lighter bracket also showing the same in inoperative position in dotted lines.

Referring to the drawings, particularly to Figs. 1 and 3. the nozzle of an ordinary blow torch is shown a, the broken dash lines at the end thereof indicating the stream of air and fuel issuing therefrom.

A lighting device is provided which comprises a stem member 1 having a forked or bifurcated end between the members of which a milled or toothed wheel 2 is mounted to rotate on a suitable pivot extending between said members. The stem 1 is formed with an internal bore and a piece of llint or spark producing material 3 is disposed to slide therein and is urged out-.

wardly against the wheel 2 by a small coiled spring 4. The stem 1 is threaded and receivcd in the threaded aperture in the bent end of a carrying member 5, a lock nut 6 being placed on the stem 1 to hold the same in its adjusted position. The member 5 comprises a flat bar or rod having angular edges and being of trapezoidal or V-shape and is adapted to slide and be frictionally held in the bracket T suitably formed to receive the same. The bracket 7 has a flat projecting tongue 7 extending from the rear thereof. and this tongue is clamped between a pair of link members 8 by a suitable headed and nutted bolt. The links 8 are, at their other ends, also clamped to a split ring 9. the apcrtured ends of which are dis posed between links and adapted to receive the headed and nutted clamping bolt. The member 9 is disposed over the nozzle of the torch. as shown in Fig. 1 and clamped thereon by tightening the clamping bolt passing therethrough.

The operation of the lighting device is as follows The bar 5 is suitably adjusted in the bracket 7 so that the lighting device is disposed in the proper spaced relation to the end of the nozzle. The clamping bolts in the links 8 are tightened so that the clamped bars are. movable about the bolts as pivots but held in any position to which they are moved by friction against the said links. The lighting device can then be swung down to the position shown in full lines in Fig. l. The wheel 2 will then be brought into contact with some adjacent surface and the torch drawn along the surface to turn said Wheel into contact therewith. The wheel will thus rotate against the spark producing member 3 and the sparks will be generated and fly ctl taiuirentially to the wheel. These sparks are illustrated by the arrows adjacent the wheel in Fig. l. and, as shown therein, the sparks will pass into the jet of air and. fuel issuing from the torch andv will readily ignite the same. litter the torch is ignited thelighter and bracket can he swung back to the position shown in dotted lines and will be retained in this position and not interfere with the normal operation of the torch.

In the modification shown in Fig. l, the lighting device comprises the stem 1 and wheel 2 is mounted in an arm 10 which is pivoted between the clamping lugs 11 of a clamping ring 11, so that the same can be swung about the clamping bolt but will be frictionally held in the position to which it is moved. The member 10 is provided with a finger hold or handle 10 by which it can be conveniently manipulated. The operas tion of the device shown in Fig. t is similar to that already described. The arms 10 will be swung down to the Full line position and the wheel 9. drawn along some convenient surface to cause the sparks therefrom to traverse the jet issuing;- ironi the torch and ignite the same. After the torch is lighted the lighting device can be swung back to the dotted line position by engaging the linger piece 10 and will then not interfere with the normal operation of the iZOIt'll.

From the above description it is seen that applicant has equipped an ordinary blow torch with an attachmenthavinggreat utility. The lighter can be (prickly swung into lighting position and the torch almost instantly lighted, after which the lighter and its carrying bracket are then swung to inoperative position.

A. great many accidents have been caused by people being burned while lightiiiig blow torches. The flame often shoots out. qu ite a distance and it the person lighting the torch is not very careful to keep out of the range of the flame he is liable to be seriously burned. some accidents have also occurred by the lighter inhaling some of the fumes before the torch is lighted and thus being quite seriously burned when the cloud of fuel was ignited. By the use oi the lighter oi this invention all danger of accident is removed as the operator need not have any part oi his person in proximity to the torch nozzle.

The device of the invention can be easily and inexpensively made and readily applied to substantially all types of blow torches. It will, of course, be understood that various changes may be made in the form, details and arrangement of the device without do parting from the scope of applicants invention, which, generally stated, consists in the matter shown and described and set forth in the appended claims.

hat is claimed is;

1. The combination with a blow torch of a lighting device comprising a bracket clamped to the body of the torch at the rear of the tip thereof, a link pivotally and trictionally secured to said bracket, a holder pivotally connected to said link and a lighting device n'iountcd on an arm slidable in said holder, whereby the lighting device can be quickly swung into position adjacent the end of the tip and moved reamvardly along the body of the torch to inoperative position.

QQThe combination with a blow tore-h oi a lighting device secured to the body of the torch by a pivoted link and a sliding member pivotally connected to the end of said link.

3. The combination with a blow torch of a lighting device, means for attaching; the same to the body of the torch rearward oi the tip thereof, means by which the device can be swung angularly in the plane of the torch and means by which the device can he slid longitudinally ol. the torch. whereby the lighter can be adjusted in proper relation to the end of the torch and can be moved to and from operative position.

In testimony whereof I afi ix my signature in presence of two witnesses.
